You could change out the whites for ATI aquablue specials, they are at 12k. I dont think you want your tank blue all the time do you? lol I hate the yellowish hue you get from 10k bulbs myself so I went with 2 aquablue specials and 2 Blue plus bulbs. I find I get a nice hue of blue and my corals can get the light they need.
